Call your doctor if there's no improvement after taking antibiotics for 48 hours. Children taking an antibiotic who feel well and don't have a fever often can return to school or child care when they're no longer contagious â usually 24 hours after beginning treatment. But be sure to finish all the medicine.
Doctors usually prescribe about 10 days of antibiotic medicine to treat strep throat. Within about 24 hours after starting on antibiotics, your child will probably no longer have a fever and won't be contagious; by the second or third day, other symptoms should start to go away. Even when kids feel better, they should continue to take the antibiotics as prescribed. Otherwise, bacteria can remain in the throat and symptoms can return. Completing all the antibiotics is the best way to prevent other health problems that a strep infection can cause, such as rheumatic fever (which can permanently damage the heart), scarlet fever, blood infections, or kidney disease.
